Sarah Palin takes on Fox News over Ted Cruz

Sarah Palin stepped up her support of Ted Cruz against other Republicans, calling on Fox News’s Chris Wallace to release the names of conservatives who he said sent in unsolicited opposition research on the Texas senator.

Palin, a Fox News commentator, tweeted on Sunday that “Fox News Sunday” should give up its “anonymous sources.”

King to Cruz: 'Keep quiet'

Who to watch

During the roundtable discussion portion of “Fox News Sunday,” after an interview with Cruz aired, Wallace revealed during a question to Republican strategist Karl Rove about conservative animosity toward Cruz that “top Republicans” had sent him opposition research against the Texas Republican.

“This has been one of the strangest weeks I’ve ever had in Washington, and I say that because as soon as we listed Ted Cruz as our featured guest this week, I got unsolicited research and questions not from Democrats, but from top Republicans who — to hammer Cruz,” Wallace said.

“Fox News Sunday” did not respond to Palin on its Twitter account.

Palin has been a strong supporter of Cruz, publishing a column on Breitbart over the weekend that praised Cruz’s efforts to defund Obamacare and slammed the “anonymous sources” who were trashing him to the press.

Cruz has been one of the leaders of the efforts on the Hill to pass a government spending bill that defunds Obamacare, which the House passed on Friday but which even Cruz has admitted has next to no chance of succeeding in the Senate. He has since threatened to filibuster the bill in the upper chamber.
